Question

我正在尝试使用SBT编译我的项目，但是我收到此错误并且无法找出原因：

YoBre$ sbt compile
[info] Loading project definition from /opt/virtualenvs/venv1/scala/name/project
[info] Set current project to name (in build file:/opt/virtualenvs/venv1/scala/name/)
[info] Compiling 4 Scala sources and 5 Java sources to /opt/virtualenvs/venv1/scala/name/target/scala-2.10/classes...

[error] three errors found
[error] (compile:compile) Compilation failed
[error] Total time: 6 s, completed 18-set-2013 12.31.36

此项目包含代码Java和Scala。当我将以前用java编写的单词文档拆分相关的功能转换为Scala时发生错误。该错误实际上与jar文件库org.apache.poi相关联。

我试图记录，但我没有找到类似的情况。

有什么想法吗？

感谢

Answer 1

您是否尝试将jar文件添加为外部依赖项？在你的build.sbt：

libraryDependencies += "org.apache.poi" % "poi-ooxml-schemas" % "3.9"

Answer 2

我已将POI版本更新为3.10-beta2。但是，没有依赖"org.apache.poi"% "-OOXML schemas"% "1.0"

添加后，一切正常

谢谢大家的答案！

  lazy val poiVersion = "3.10-beta2"
  lazy val libPoi ="org.apache.poi" % "poi" % poiVersion
  lazy val libPoiScratchpad ="org.apache.poi" % "poi-scratchpad" % poiVersion
  lazy val libPoiOOXML ="org.apache.poi" % "poi-ooxml" % poiVersion
  lazy val libPoiOOXMLSchema= "org.apache.poi" % "ooxml-schemas" % "1.0"
  lazy val libPoiComponents = Seq(libPoi, libPoiScratchpad, libPoiOOXML, libPoiOOXMLSchema)

Answer 3

我找到了similar question，我怀疑你可能有同样的问题。 Scala无法加载缺少注释的类，因此可能存在缺少的依赖项，否则Java是可选的。

通过在sbt中执行show compile:dependency-classpath来检查您的依赖关系列表，并确保您已在Apache POI Project site列出所有先决条件。

使用Scala使用poi-ooxml-schemas-3.9.jar编译错误
